New File New File
The "New File" button is used to start a new file. When clicked, a number of options are available:
Restart Current File - Clears the content of the current HTML Editor window
Begin a New File - Opens a new "Tab", allowing you to start a new file, whilst retaining the current file in a separate "Tab"
Duplicate Current File - Opens a new "Tab", and duplicates the content of the current tab into the new tab. This feature is useful to try new things with your code and make easy "before-and-after" comparisons
